Abstract: 341,557. Casting-machines. STONE & CO., Ltd., J., Deptford, POWER, A. S., 11, Haycroft Gardens, Harlesden, and LUDBROOK, R., Rokeby House, Rokeby Road, Brockley, all in London. Oct. 22, 1929, No. 32067. [Class 83 (i).] Clamping moulds.-A die-casting machine has a vertical chamber e to receive molten metal, a loose cam or block forming a bottom for the chamber, a mould m applicable to the upper end of the chamber, and a plunger c that actuates the loose cam to charge the mould. A valve g, Fig. 5, has passages opening into a central bore of which 7, 8 are connected to a hydraulic pressure supply w, 9, 10, Fig. 7, are connected to exhaust x, 1a and 1b, Fig. 6, are connected to a pipe 1 leading to the rear of a cylinder D, Fig. 1, and 4a and 4b are connected to a pipe 4 leading to the other end of the cylinder D. Similar passages 2a, 2b, 5a, 5b, 3b, 6a, and 6b are connected to pipes 2, 5, 3, and 6, leading to cylinders E, F, respectively. Fluid from a hand-operated valve h is supplied through a pipe k with a constriction k<1>, Fig. 5, to move a plunger j slowly to the right thus connecting the passage 7 to 1b and 10 to 4b by grooves 11, 11a and breaking the connection 8 to 4a and 9 to 1a. This causes the piston A to move to the right and clamp the chamber e to the stop d. The chamber is then filled with molten metal and the mould m placed thereon. Further movement of the plunger acts similarly to cause a piston B to move down and clamp the mould m to the chamber e and then a piston C to move up and force the molten metal into the mould. The operation may be arrested after the piston A or B has moved by moving the valve h into neutral position. The valve h is finally moved into position to admit pressure to a pipe l and exhaust k thus rapidly returning the plunger j to the position shown, in which the connections previously made are broken and the passages 7, 8 are connected to 4a, 5a, and 6a and the passages 9, 10 to 1a, 2a, and 3a, thus moving the pistons A, B, C back to the position shown in Fig. 1.

Title: Improvements in internal-combustion engines provided with exhaust turbines and compressors
IPC: F02B37/02
Filed: 1925-12-23
Abstract: 245,151. B³chi, A. Dec. 24, 1924, [Convention date]. Motor power plant.-In a four-stroke internalcombustion engine 48, charged by a pre-compressor 40, Fig. 5, before, the end of the expansion stroke a valve 51 admits exhaust gases by way of a conduit 49 and nozzles 52 to a turbine I, and during the exhaust stroke of the engine the valve 51 is closed and a valve 44 admits the remaining exhaust gases through a conduit 53 to a lower-pressure turbine II receiving also the exhaust from the turbine I. The turbine I, II may be independent, or inter-geared with the engine, and may drive the compressor 40 and an electric generator 60. Fig. 6 shows the application of the invention to a two-stroke engine, the turbine I being supplied with exhaust gases from a pipe 49 and valve 51, and the turbine II with exhaust gases which are scavenged through ports 44 and a pipe 53 by the pre-compressed charge or air admitted through a pipe 42 and ports 47. In another two-stroke engine, Fig. 7, the compressed charge is introduced through a row of ports 47 and an upper row of ports 47<a> controlled by a valve 47<b>. On the downward movement of the piston a valve 51 opens and admits exhaust gases to the pipe 49 and turbine I. Then the pre-compressed charge entering the cylinder through ports 47 scavenges the exhaust gases through ports 44 and a conduit 53 to the turbine II. Finally the valve 47<b> opens, admitting a fresh charge also through the upper ports 47<a>. Scavenging into both turbines I, II may be employed. At certain loads the exhaust gases may be led to the turbine II only. With multi-cylinder engines, separate conduits lead from each cylinder to the turbine I.

Abstract: 1417600 Folding apparatus MASCHINENFABRIK GOEBEL GmbH 9 July 1973 [10 July 1972] 32550/73 Heading B8R In a zig-zag folding apparatus having swing- ing folding funnels 5 and 5<SP>1</SP> the swinging movement is derived from eccentrics 8, 9 and 8<SP>1</SP>, 9<SP>1</SP> linked to opposite side edges of the funnels by members 6, 7 and 6<SP>1</SP>, 7<SP>1</SP> respectively, the eccentrics being adjustable relative to drive means therefor so that the amplitude of the swing may be varied. To this end the eccentrics 8, 9 are slotted at 12 to receive a screw 13 which is coupled to a drive shaft 17. The drive shaft has a flange 27 carrying a serrated plate 19 which meshes with serrations in a lug 33 at the rear of the eccentric 8. To adjust the eccentrics the screw 13 is slackened sufficiently to permit the serrations to disengage. A further eccentric 36 movable about a shaft 35 is connectible to the eccentrics 8 and 9 by displacement of the eccentric 36 leftwards (as viewed in Fig. 1) until link 37 engages recess 38 in a disc 39 contacting the eccentric 9. Movement of eccentric 36 about shaft 35 (by means of lever 41) causes displacement of the eccentrics 8 and 9 relative to screw 13. In the left hand position the eccentric 36 engages a limit switch 40 which stops the main drive of the machine. The eccentrics 8<SP>1</SP>, 9<SP>1</SP> and the members 6<SP>1</SP>, 7<SP>1</SP> are arranged similarly at the opposite side edge of the funnels so that both sets of eccentrics impart identical reciprocating movement to the funnels along opposite side edges of the web being folded.

Patent GB-743960-A (GB)
Title: Improvements in or relating to catalyst bases
IPC: B01J21/04
Filed: 1953-11-24
Abstract: In the process for the production of alumina claimed in the parent Specification, the anhydrous aluminium alcoholate solution is contacted with carbon dioxide prior to hydrolysis.  Carbon dioxide may be bubbled through the anhydrous solution, solid carbon dioxide may be added, or the solution may be treated with carbon dioxide under pressure; a suitable range of temperature for this treatment is 50-150 DEG F.  The hydrolyzing liquid may also contain carbon dioxide, and the pH of the aqueous phase during hydrolysis is preferably 4.0-5.5.  The alumina formed may be dried at 220 DEG -500 DEG F. and activated at 900 DEG -1400 DEG F. for 1-12 hours.  It has a base volume of 0.25-0.55 ccs. per gram, a surface area of 100-250 sq. metres per gram, and an average pore diameter of 60-150 ; the attrition rate is lower than that of alumina prepared without the addition of carbon dioxide.  Hydroforming catalysts are prepared by impregnating the aluminia with a Group VI metal oxide (e.g. 10 per cent molybdenum) or with a platinum group metal.  In an example, aluminium is dissolved in a mixture of amyl alcohols and petroleum naphtha using mercuric chloride as catalyst, and the solution is saturated with carbon dioxide and hydrolized with water.

Title: Improvements in or relating to thermionic oscillators
IPC: H03K7/00
Filed: 1935-11-25
Abstract: 448,762. Valve modulating circuits. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN, Emmasingel, Eindhoven, Holland. Nov. 25, 1935, No. 32641. Convention date, Dec. 17, 1934. [Class 40 (v)] In a thermionic oscillator of the kind in which the frequency depends on the transit time of an electron, and tends to vary with the modulating-voltage applied to its electrodes, e.g. a magnetron or Barkhausen-Kurz oscillator, the modulation voltage is broken up into intermittent pulses at a medium frequency, the length of each pulse being dependent on the momentary value of the modulating-voltage. This avoids frequency changes, and overcomes other difficulties due to the valve ceasing to oscillate. Fig. 2 shows a magnetron oscillator 1 with its anode voltages supplied by a source 2 through a resistance or choke 3. A valve 4 has its plate-filament path in shunt to the oscillator, 1 and its grid voltage is supplied by the microphone 6 in series with a generator 5 giving a frequency higher than the highest modulation frequency. The effect of combining the microphonic voltage 7 with the voltage of the generator 5 is shown in the curve 8 of Fig. 3. The horizontal line 9 represents the grid voltage at and above which the valve 4 is conductive, and the heavy-line intercepts of the curve 8 on this line represent the periods during which valve 4 is conductive, the lengths of these periods being variable in dependence on the modulating-voltage 7. Whilst the valve 4 is conductive only a low voltage reaches the oscillator anodes, so that oscillation is feeble or ceases. During the non-conductive periods of the valve 4, the oscillator operates at a constant amplitude.

Title: Improvements in and relating to washing machines
IPC: D06F23/04
Filed: 1938-11-10
Abstract: 508,645. Centrifugal machines. BRITISH THOMSON-HOUSTON CO., Ltd. Nov. 10, 1938, No. 32650. Convention date, Nov. 11, 1937. [Class 23] [Also in Group VIII] In a machine wherein a receptacle 33, Fig. 1, is held stationary whilst an agitator 62 eccentrically mounted therein is moved unidirectionally in an orbital path for washing the goods contained in the receptacle, and wherein the receptacle is rotated at high speed for centrifuging, the direction of rotation of the shaft 10, about which the agitator and receptacle are mounted and which is driven from a reversible motor, determines which of these motions shall result. The motor 89, Fig. 6, drives a pulley 87 keyed to a sleeve 86 which is connected to a shaft 8 through a one-way clutch 104. A pinion 90 integral with the sleeve 86 drives another gear-wheel 98 through reduction gear 91 &c., and this gear-wheel is connected to the shaft 8 through another oneway clutch 102 which acts in the opposite sense to the clutch 104. The shaft 8 drives the shaft 10 through a universal coupling 9, 15, Fig. 1. The agitator is carried in bearings 55, 56 secured to a sleeve 46 which is splined to the top of the shaft 10, the lower end of the sleeve being formed as a plate 51 having an eccentric depression 50 adjacent the lower edge of the agitator. The receptacle, which is provided with an internal annular member 53 adjacent the downwardly turned edge of the disc 51, is carried by another sleeve 34. A one-way driving connection 108 is provided between the shaft 10 and the sleeve 34 such that when the shaft 10 is rotating in the direction wherein it is rotated at high speed by the clutch 104, the sleeve 34 and consequently the receptacle 33 are also rotated at high speed. When the shaft 10 is rotating slowly in the reverse direction, the clutch 108 does not transmit the motion to the sleeve 34 and receptacle, but in order to prevent the tendency of the receptacle to follow up the movement of the agitator, a locking device 69, 71 acting automatically and in one direction only is provided between the sleeve 34 and a fixed part. This tendency of the receptacle to move being in the opposite direction to that in which the receptacle rotates during centrifuging, the one-way locking device 69, 71 does not interfere with the high-speed rotation of the receptacle.
